Power connections
Power can be supplied to the camera by the following methods:
• The supplied power adapter, PS-K, 9W. The center pin is positive (+).
• Power over Ethernet (PoE) with power classification Class 2, via the network cable. This will automati-
cally be detected if available via the network.
• The power connector block on the rear panel.
Power Connector Block
The power connector block supports both AC and DC input power.
The DC supply is 7-24V. Connect the negative pole to the GND pin and the positive pole to the DC+ pin.
Pin Function Description
1 Output A On the external device output terminals (A and B), there is no distinction between positive and negative
(+ and -). The terminals use a photocoupler and are electrically isolated from the other internal circuitry.
The maximum load should not exceed 100mA and the maximum voltage should be not more than 50V
DC. Note: Connecting AC to the output will damage the unit.
2Output B
3 Digital Input 1- Photocoupler Anode (+) Photocoupled Input 1. Electrically isolated from the chassis and connectors, this input can be supplied
from an external DC voltage or the DC Power Input/Output on pins 9 (DC+) and 10 (GND).
4 Digital Input 1 - Photocoupler Cathode (-)
5 Digital Input 2 - Photocoupler Anode (+) Photocoupled Input 2. As above.
6 Digital Input 2 - Photocoupler Cathode (-)
7 RS-485-A (non-inverting) A half-duplex RS-485 interface for controlling auxiliary equipment.
8 RS-485-B (inverting)
9 DC + Power Output This can drive the photocoupler inputs or other equipment. The output voltage level is 3.0 V. A maximum
current of 100mA can be sourced from the DC output.
10 GND Ground.
